获取后台用户 token 的方法

一，通过电子邮箱获取用户token

protected function getCustomerToken($emailId){
 /**
* @var MagentoCustomerModelCustomer $customer */
*/
$customer->loadByEmail($emailId);
if($customer->getId()){
        /**
        * @var MagentoIntegrationModelOauthTokenFactory $tokenModelFactory 
        */
        $customerToken = $this->tokenModelFactory->create();
        $tokenKey = $customerToken->createCustomerToken($customerId)->getToken();
        return $tokenKey;
}
return "YOU MSG FOR CUSTOMER NOT FOUND";
}

二、通过用户名和密码获取token

public function getToken($username,$password)
{
    $objectManager = MagentoFrameworkAppObjectManager::getInstance();
    $token = $objectManager->get('MagentoIntegrationModelAdminTokenService')->createAdminAccessToken($username,$password);
    return $token;
}
